Abstract
Description
Technical field
[0001] The present disclosure relates to a vehicle control unit and a vehicle control procedure. State of the art
[0002] When an ignition key is switched from an OFF state to an ON state, a conventional control device drives a motor that applies a steering assist torque to a steering mechanism after a diagnostic process has been carried out by a control calculation unit that calculates a current for the motor (for example, Japanese Disclosure Document No. 2008-13146). Brief description of the invention; task to be solved by the invention
[0003] If a memory is configured to store diagnostic results from various devices present in a vehicle after a driver has initiated an OFF operation to turn the ignition key to the OFF state, there is a possibility that the driver could initiate an ON operation to turn the ignition key back to the ON state while the diagnostic results are being stored. In such a case, the control unit may restart the vehicle by interrupting the process due to the driver's ON operation, potentially leading to a problem where a device being diagnosed is incorrectly identified as faulty based on inaccurate diagnostic results stored in memory.
[0004] The present disclosure focuses on this point, and one of its objectives is to restart a vehicle at a suitable time. SOLUTION TO THE TASK
[0005] A vehicle control unit according to a first aspect of the present disclosure comprises a receiver unit that receives an ON operation to cause an electronic device contained in a vehicle to be switched on, and an OFF operation to cause the activated electronic device to be switched off, and a controller that controls the switching on or off of the electronic device based on an operation received from the receiver unit, wherein, if the receiver unit receives the ON operation before a predetermined time has elapsed since the receiver unit received the OFF operation, the controller causes the electronic device to initiate the switching on after the predetermined time has elapsed since the receiver unit received the OFF operation.
[0006] If the receiving unit receives the ON signal after the specified time has elapsed since the receiving unit received the OFF signal, the control can cause the electronic device to initiate the switching-on process at a time when the ON signal is received.
[0007] The vehicle control unit can be a device that controls the vehicle including a power source including a motor, and the control unit can control the switching on and off of the electronic device, which is a control unit for controlling the motor.
[0008] The preset time may be equal to or longer than the time required for the electronic device controlling the motor to complete the shutdown after the receiving unit has received the OFF operation, and the vehicle control unit may further include a memory that stores the preset time.
[0009] After the receiving unit receives the ON signal before the predetermined time has elapsed, after the receiving unit receives the OFF signal, the control can cause the electronic device to initiate the switching-on process after the predetermined time has elapsed, provided that the receiving unit does not receive the OFF signal before the predetermined time has elapsed.
[0010] The vehicle control unit may also include a display control which causes a display unit to show a message indicating that the predetermined time has not yet elapsed, based on the fact that the receiving unit receives the ON operation before the predetermined time has elapsed after the receiving unit receives the OFF operation.
[0011] The display control can hide the message after the specified time has elapsed since the receiving unit received the OFF command.
[0012] The display control can hide the message if the receiving unit receives the OFF operation before the specified time has elapsed after the receiving unit has received the ON operation within the specified time after receiving the OFF operation.
[0013] The display control can cause a message indicating that the electronic device will not turn on to be displayed if the receiving unit receives the OFF operation before the specified time has elapsed after the receiving unit has received the ON operation within the specified time following the receipt of the OFF operation by the receiving unit.
[0014] A vehicle control method according to a second aspect of the present disclosure is a vehicle control method executed by a processor and comprising the following steps: receiving an ON operation to cause an electronic device contained in a vehicle to be switched on, and an OFF operation to cause the activated electronic device to be switched off, and controlling the switching on or off of the electronic device based on an operation received at the time of reception, wherein, if the ON operation is received before a predetermined time has elapsed after the OFF operation was received at the time of reception, the switching on of the electronic device is initiated after the predetermined time has elapsed after the OFF operation was received at the time of control. Effect of the invention
[0015] According to the present disclosure, the vehicle can be restarted at a suitable time. Brief description of the drawings Fig. Figure 1 shows an overview of a vehicle control system S according to the present embodiment. Fig. Figure 2 shows a process in which an MCU 4 initiates the power-on process after a predetermined time has elapsed. Fig. Figure 3 shows a process in which a controller 122 does not initiate the switching on of the MCU 4 due to an error in fulfilling a predefined condition. Fig. Figure 4 shows a process in which the MCU 4 initiates the power-on process at a time when an ON request is received. Fig. 5 is an example of a message indicating that a given time P has not yet elapsed. Fig. 6 is an example of a message indicating that MCU 4 will not turn on. Fig. Figure 7 shows an example of a processing sequence in a VCU 10. Description of the embodiments; Overview of the vehicle control system S
[0016] Fig. Figure 1 shows an overview of a vehicle control system S according to the present embodiment. The in Fig. The vehicle control system S shown comprises a control unit 1, a motor 2, an inverter 3, an electronic device 4, a memory 5, a display unit 6, and a vehicle control unit 10. The vehicle control system S is installed in a vehicle and has the function of controlling the operation of a drive source contained in the vehicle. The drive source is the motor 2.
[0017] The control unit 1 includes an ignition key or switch for starting or stopping the vehicle's drive source, which is equipped with the vehicle control system S, and the vehicle's accelerator pedal. The motor 2 is an electric motor that converts electrical energy into mechanical energy (kinetic energy) and is the drive source for propelling the vehicle, which is equipped with the vehicle control system S. The inverter 3 is a circuit for converting direct current power, output by a battery located in the vehicle (not shown in the figures), into alternating current power and supplying the alternating current power to the motor 2.
[0018] The electronic device 4 is a control unit that controls the motor 2 and is a so-called motor control unit (MCU). The electronic device 4 detects i) the amount of depressurization of the accelerator pedal by a driver of the vehicle, ii) the current value of the AC power supplied to the motor 2 by the inverter 3, and iii) an angular value, detected, for example, by a resolver (angle displacement sensor) contained in the motor 2. The electronic device 4 then generates a pulse width modulation (PWM) signal based on the detected amount of depressurization, current value, and angular value and outputs the generated PWM signal to the inverter 3, thereby controlling the output of the motor 2.
[0019] The electronic device 4 diagnoses at regular intervals whether a fault has occurred in the inverter 3. For example, the electronic device 4 detects a synthesized voltage, obtained by combining the output voltages of the respective phases of the inverter 3 as a virtual neutral point voltage corresponding to the neutral point of the motor 2, and diagnoses the inverter 3 based on this synthesized voltage. The electronic device 4 stores a diagnostic result in memory 5, which is obtained by diagnosing whether a fault has occurred in the inverter 3 or not.
[0020] Memory 5 is a storage medium, such as an electrically erasable and programmable read-only memory (EEPROM). Memory 5 stores various types of information required by the electronic device 4 to control the motor 2 and the inverter 3. Memory 5 stores the diagnostic result obtained by the electronic device 4 diagnosing the inverter 3. Display unit 6 is a display located in the vehicle's instrument panel and is, for example, a multi-information display.
[0021] The vehicle control unit 10 is a device that controls the vehicle, which is equipped with the drive source including the motor 2, and is a so-called vehicle control unit (VCU). The vehicle control unit 10 has the function of turning the electronic device 4 on and off as a result of the driver of the vehicle operating the ignition key or switch contained in the control unit 1.
[0022] For example, the vehicle control unit 10 sends a start signal to the electronic device 4 via a Controller Area Network (CAN) to cause it to switch on, and a shutdown signal to cause it to switch off. For example, upon receiving the ON action performed by the driver to turn the ignition key or to switch the control unit 1 to the ON state, the vehicle control unit 10 sends the start signal to the electronic device 4 to cause it to switch on. For example, upon receiving the OFF action performed by the driver to turn the ignition key or to switch the control unit 1 to the OFF state, the vehicle control unit 10 sends the shutdown signal to the electronic device 4 to cause it to switch off.
[0023] When the electronic device 4 receives the shutdown signal from the vehicle control unit 10, it performs a shutdown operation (hereinafter referred to as the "shutdown operation") and then stops. This operation requires a predetermined time period (for example, 10 seconds) from receiving the shutdown signal until it stops. As an example, the shutdown operation is an operation of storing the diagnostic result obtained by diagnosing whether or not a fault has occurred in inverter 3 in memory 5. Therefore, if the start signal is received from the vehicle control unit 10 while the shutdown operation is in progress, the electronic device 4 interrupts the operation of storing the diagnostic result in memory 5 and initiates a restart. Thus, the electronic device 4 may erroneously use the diagnostic result that was partially stored in memory 5 (i.e.,(of a false diagnostic result), determine that a fault has occurred in Inverter 3.
[0024] Furthermore, if the ON signal is received by the control unit 1 before a predetermined time has elapsed after the OFF signal was received by the control unit 1, the vehicle control unit 10 accordingly issues the start signal after the predetermined time has elapsed. The predetermined time is, for example, a time equal to or longer than the time required for the electronic device 4 to complete the shutdown process. By controlling the timing at which the vehicle control unit 10 causes the electronic device 4 to restart in this manner, the vehicle control unit 10 can prevent the electronic device 4 from incorrectly determining that the inverter 3 is faulty.
[0025] The design and operation of the vehicle control unit 10 are described in detail below. In the following description, the electronic device 4 is referred to as "MCU 4", and the vehicle control unit 10 is referred to as "VCU 10". <Ausgestaltung der VCU 10>
[0026] As in Fig. As shown in Figure 1, the VCU 10 comprises a memory 11 and a processor 12. The processor 12 includes a receiver 121, a controller 122 and a display controller 123.
[0027] Memory 11 comprises a storage medium such as read-only memory (ROM), random access memory (RAM), a hard disk drive (HDD), or a solid-state drive (SSD). Memory 11 stores a program executed by processor 12 and various types of information for controlling the timing of power-on and power-off of the MCU 4.
[0028] Processor 12 is a processor such as a central processing unit (CPU) or an electronic control unit (ECU). Processor 12 acts as the receiver 121, the controller 122, and the display controller 123 by executing the program stored in memory 11. Processor 12 can consist of a single processor, multiple processors, or a combination of one or more processors and an electronic circuit.
[0029] The receiver 121 receives the ON operation to turn on the MCU 4 and the OFF operation to turn off the activated MCU 4. For example, the receiver 121 receives the ON operation from the control unit 1 as an operation to turn on the MCU 4, where the ON operation indicates that the driver has turned on the ignition key or switch of the control unit 1. For example, the receiver 121 receives the OFF operation from the control unit 1 as an operation to turn off the MCU 4, where the OFF operation indicates that the driver has turned off the ignition key or switch of the control unit 1.
[0030] Controller 122 controls the switching on or off of MCU 4 based on the operation received by receiver 121. For example, controller 122 controls the timing of initiating the shutdown of MCU 4 following the receipt of the OFF operation by receiver 121. Controller 122 controls the shutdown of MCU 4, which is a control unit for motor 2, by outputting the shutdown signal to MCU 4 at the time receiver 121 receives the OFF operation, or, for example, at a subsequent time.
[0031] For example, the controller 122 controls the timing of the initiation of the power-on of the MCU 4 following the receipt of the ON operation by the receiver unit 121. The controller 122 controls the power-on of the MCU 4, which is a control unit for controlling the motor 2, by outputting the start signal to the MCU 4 after the receiver unit 121 receives the ON operation.
[0032] If receiver 121 receives the ON command before the predetermined time has elapsed since receiving the OFF command, controller 122 causes MCU 4 to initiate the ON process after the predetermined time has elapsed since receiver 121 received the OFF command. The predetermined time is equal to or longer than the time required for MCU 4, which controls motor 2, to complete the shutdown process after receiver 121 received the OFF command, and is, for example, 10 seconds. The predetermined time is stored in memory 11.
[0033] For example, if receiver 121 receives the ON signal before the predetermined time has elapsed since the initial OFF signal received by receiver 121, controller 122 causes MCU 4 to initiate the power-on process after the predetermined time has elapsed since that initial signal. In other words, if receiver 121 receives the ON signal before the predetermined time has elapsed since the initial signal, controller 122 outputs the start signal after the predetermined time has elapsed to cause MCU 4 to initiate the power-on process.
[0034] Fig. Figure 2 shows a process in which the MCU 4 initiates the power-on process after the specified time has elapsed. The horizontal axis of Fig. 2 represents time, and the vertical axis of Fig. 2 represents a “process”, indicating the operation (ON operation or OFF operation) received from the operator unit 1, an “MCU”, indicating the process state of the MCU 4, and a “message”, indicating whether the display controller 123 causes the message to be displayed on the display unit 6 or not. The in Fig. The time T1 shown is the first point in time, and the time T2 is a second point in time, which is a time at which a given time P has elapsed since time T1. A in Fig. Figure 2, "Shutdown Procedure," comprises a state in which the shutdown procedure is in progress and a state in which the MCU 4 is in a stopped state after the shutdown procedure has been completed. Details of the "message" that is caused to be displayed on the display unit 6 by the display controller 123 are described later.
[0035] As in Fig. As shown in Figure 2, when receiver 121 receives the OFF signal at time T1, controller 122 outputs the shutdown signal to MCU 4 at time T1 or at a time following time T1, causing MCU 4 to initiate the shutdown process. Subsequently, receiver 121 receives the ON signal at time T3, before the predetermined time P has elapsed from time T1, and controller 122 outputs the start signal at time T2, that is, after the predetermined time P has elapsed from time T1. MCU 4 then initiates the power-on process by detecting the start signal at time T2.
[0036] If the controller 122 operates as described above, the MCU 4 can initiate the power-on process after the shutdown process is complete, even if the driver performs the power-on operation before the shutdown process is finished. As a result, the controller 122 prevents the MCU 4 from initiating a restart, for example, in a state where incorrect data is stored in memory 5. Furthermore, the controller 122 is able to cause the MCU 4 to power on after the MCU 4 has completed the shutdown process, even if the VCU 10 cannot be notified of the shutdown process's completion after the MCU 4 has finished. Consequently, the VCU 10 can restart the vehicle at a suitable time.
[0037] For example, if a predefined condition is met after receiver unit 121 receives the ON signal before the predefined time P has elapsed since receiving the OFF signal, the controller 122 causes the MCU 4 to initiate the power-on process after the predefined time P has elapsed. The predefined condition is that receiver unit 121 does not receive the OFF signal before the predefined time P has elapsed. For example, as in Fig. As shown in Figure 2, if the receiving unit 121 does not receive the OFF operation during a period from time T3, at which the receiving unit 121 receives the ON operation, until time T2, at which the specified time P has elapsed, the control unit 122 causes the MCU 4 to initiate the switching on at time T2.
[0038] If, on the other hand, the receiving unit 121 initiates the OFF process during the in Fig. During the time shown in 2, from time T3 to time T2, the controller 122 does not cause the MCU 4 to initiate the switch-on at time T2 due to an error in fulfilling the specified condition. Fig. Figure 3 shows a process where the controller 122 fails to cause the MCU 4 to initiate power-on due to an error in meeting the specified condition. The horizontal and vertical axes in Fig. 3 are the same as the horizontal axis and the vertical axis in Fig. 2. The time T1, the time T2 and the time T3, which are in Fig. The times shown in 3 are the same as time T1, time T2, and time T3, which are in Fig. 2 are shown. If, as in Fig. As shown in Figure 3, when the receiver 121 receives the OFF signal at time T4, which falls within the period from time T3 to time T2, the controller 122 does not output the start signal at time T2. Consequently, the MCU 4 does not initiate the power-on process after time T2.
[0039] By operating as described above, the controller 122 is able to control whether the MCU 4 should be instructed to initiate the power-on process after the predetermined time period P has elapsed, in accordance with the driver's action, even during the predetermined time P at which the MCU 4 performs the power-off operation. Consequently, the controller 122 is able to control the MCU 4 so that it does not initiate the power-on process according to the driver's action, even in a case where the driver mistakenly performed the ON operation during the predetermined time P and subsequently, for example, performed the OFF operation.
[0040] The controller 122 can control the power-on of the MCU 4 based on the operation closest to time T2, among several operations received by the receiver 121 before time T2, which is a time after the predetermined time P has elapsed from time T1. For example, the controller 122 causes the MCU 4 to initiate power-on at time T2 if, among the several operations received by the receiver 121 during the predetermined time P, the operation closest to time T2 is the ON operation. Conversely, the controller 122 does not cause the MCU 4 to initiate power-on at time T2 if, among the several operations received by the receiver 121 during the predetermined time P, the operation closest to time T2 is the OFF operation.
[0041] By operating as described above, even if the driver erroneously performs the ON and OFF operations multiple times during the specified time P, the controller 122 can control the activation of the MCU 4 based on the operation last performed by the driver during the specified time P. Consequently, the controller 122 is able to compare the operating state of the control unit 1, as performed by the driver, with the active or stopped state of the MCU 4 at time T2.
[0042] If the receiver 121 receives the ON signal after the predetermined time P has elapsed since receiving the OFF signal (i.e., after time T2, which is the second time), the controller 122 causes the MCU 4 to initiate the power-on process at the time the ON signal is received. That is, if the receiver 121 receives the ON signal after time T2, the controller 122 outputs the start signal at the time the ON signal is received to cause the MCU 4 to initiate the power-on process.
[0043] Fig. Figure 4 shows a process where MCU 4 initiates the power-on process at the time the ON command is received. The horizontal and vertical axes in Fig. 4 are the same as the horizontal axis and the vertical axis, which are in Fig. Figure 2 shows the time T1 and time T2, which are shown in Fig. The values shown in 4 are the same as time T1 and time T2, which are shown in Fig. 2 are shown. As in Fig. As shown in Figure 4, when the receiver unit 121 receives the ON command at time T5, which is a time after time T2, the controller 122 outputs the start signal at time T5 or at a time following time T5. The MCU 4 then initiates the power-on process by detecting the start signal. The controller 122 operates as described above, so that the MCU 4 can power on without delay from the time of the driver's ON command after the power-off process is completed.
[0044] The display control 123 controls whether a message is displayed on the display unit 6 or not. For example, the display control (123) causes the display unit (6) to display a message indicating that the predetermined time (P) has not yet elapsed because the receiver unit (121) receives the ON signal before the predetermined time (P) has elapsed after receiving the OFF signal (i.e., from time T1, which is the first time). The message is, for example, text data, but it can include an image or a moving image, or it can be an image or a moving image that corresponds to the text data.
[0045] Fig. 5 is an example of the message indicating that the specified time P has not yet elapsed. As in Fig. As shown in Figure 5, the display controller 123 causes the display unit 6 to display a message indicating that the MCU 4 is in the startup process, rather than a message indicating that the predetermined time P has not yet elapsed (i.e., the MCU 4 is in the shutdown process). Since the driver might assume that the shutdown process has been completed after the OFF operation, displaying a message related to the shutdown process by the display controller 123 when the ON operation is performed after the OFF operation can make it difficult for the driver to understand the vehicle's state. Accordingly, the display controller 123 displays a message indicating that the startup process is in progress, instead of indicating that the predetermined time P has not yet elapsed, thus making it easier for the driver to understand the vehicle's state.
[0046] For example, as in Fig. As shown in 2, the display control 123 causes the display unit 6 to display, which is in Fig. The 5-point message shown is displayed for a period of time from time T3, when the receiver 121 receives the ON signal, until time T2, when the predetermined time P has elapsed. Then, the display controller 123 hides the message after the predetermined time P has elapsed since the receiver 121 received the OFF signal. For example, the display controller 123 causes the message to be hidden after time T2 (i.e., after the second time the predetermined time P has elapsed since the first time). By operating in this manner, the display controller 123 is able to notify the driver of the vehicle's status during a period of time when a vehicle action differs from a corresponding action of the driver.
[0047] For example, if the receiving unit 121 receives the ON operation before the predetermined time P has elapsed after receiving the OFF operation (i.e., from time T1, which is the first time), the display controller 123 hides the message if the receiving unit 121 receives the OFF operation before the predetermined time P has elapsed. For example, if the receiving unit 121 receives the OFF operation at the time specified in Fig. Upon receiving the message shown at time T4, the display control 123 hides the message after time T4. By operating in this way, the display control 123 can hide the message according to the driver's actions, thus allowing the driver to easily assess the vehicle's status.
[0048] The display controller 123 can cause the display unit 6 to show a message indicating that the MCU 4 will not turn on if the receiver unit 121 receives the OFF command before the predetermined time P has elapsed from time T1 after it received the ON command within the predetermined time P. For example, the display controller 123 causes the message indicating that the MCU 4 will not turn on to be displayed if the receiver unit 121 receives the OFF command before the predetermined time P has elapsed after it received the ON command within the predetermined time P after receiving the OFF command.
[0049] Fig. 6 is an example of the message indicating that MCU 4 will not turn on. As in Fig. As shown in Figure 6, the display controller 123 causes the display unit 6 to display a message indicating that the MCU 4 has stopped the power-on process, rather than a message indicating that the MCU 4 will not power on. For example, if the receiver unit 121 receives the OFF operation from the display unit 6, the display unit 6 will display a message indicating that the MCU 4 will not power on. Fig. When time T4 receives the information shown in point 3, the display control 123 causes the information shown in Fig. The message shown is displayed at time T4 or at a time following time T4.
[0050] By operating in this manner, the display control 123 can notify the driver that the vehicle is being operated according to the driver's instructions. Furthermore, the display control 123 indicates that the MCU 4 has stopped the power-on process, instead of indicating that the MCU 4 will not power on after time T2 (the second time point), thus informing the driver of the vehicle's status using a message that is easier for the driver to understand. <Verarbeitungssequenz in der VCU 10>
[0051] Fig. Figure 7 shows an example of a processing sequence in the VCU 10. The in Fig. The processing sequence shown in Figure 7 is a processing sequence that shows an operation in which the VCU 10 causes the MCU 4 to initiate the power-on process.
[0052] If the OFF command is received by control unit 1 (YES in step S11), receiver unit 121 outputs the shutdown signal to MCU 4 to cause MCU 4 to initiate the shutdown process (step S12). If the OFF command is not received by control unit 1 (NO in step S11), receiver unit 121 repeats the process from step S11.
[0053] If receiver unit 121 does not receive the ON operation (NO in step S13), receiver unit 121 repeats the operation of step S13. If receiver unit 121 receives the ON operation (YES in step S13), controller 122 determines whether the predetermined time has elapsed since the operation of step S11 (step S14). If it is determined that the predetermined time has elapsed (YES in step S14), controller 122 sends the start signal to MCU 4 to cause MCU 4 to initiate the power-on process (step S15).
[0054] If it is determined that the specified time has not yet elapsed (NO in step S14), the display control 123 instructs the display unit 6 to display a Fig. 5. The display shows the “message indicating that the start process is in progress” (step S16). If it is then determined that the specified time since the process of step S11 has not yet elapsed (NO in step S17), the controller 122 repeats the process of step S17. If it is determined that the specified time has elapsed (YES in step S17), the display controller 123 hides the message shown in Fig. 5 shown “message indicating that the start-up process is underway” (step S18), and the controller 122 causes the MCU 4 to initiate the start (step S15). <Wirkung der VCU 10>
[0055] As described above, the VCU 10 includes i) the receiver 121, which receives the ON operation to turn on the MCU 4 contained in the vehicle, and the OFF operation to turn off the activated MCU 4, and ii) the controller 122, which controls the turning on or off of the MCU 4 based on the operation at the receiver 121. If the receiver 121 receives the ON operation before the predetermined time has elapsed since receiving the OFF operation, the controller 122 causes the MCU 4 to initiate the turning-on operation after the predetermined time has elapsed since the receiver 121 received the OFF operation.
[0056] If the VCU 10 is configured as described above, the MCU 4 can initiate the power-on process after the shutdown process has completed, even if the driver initiates the power-on process before the shutdown process is finished. Consequently, the VCU 10 can restart the MCU 4 after the MCU 4 has stored the correct data in memory 5 during the shutdown process, thus preventing the erroneous determination that the device controlled by the MCU 4 (for example, inverter 3) is faulty. In other words, the VCU 10 can restart the vehicle, including the MCU 4, at an appropriate time.
